Embodiment 1
[0070] (1) Synthetic acrylic water-based resin:
[0071] Process: Add xylene solvent and 20 parts of mixed monomers, pass nitrogen gas, heat up to 100°C, add various monomers and some initiator dibenzoyl peroxide (BPO) dropwise, keep warm for 1 hour, add dropwise Keep the remaining initiator at high temperature (130°C) for 3 hours, measure the conversion rate (99%), remove the solvent, remove the solvent under negative pressure, lower the temperature, add DC-3AD modified polysiloxane surfactant, and add deionized water , stir to disperse, control the solid content, filter and pack for later use. The ratio of the main raw material mixed monomers: 55 parts of methyl methacrylate, 25 parts of methacrylic acid, 5 parts of acrylic acid, 15 parts of 2-ethylhexyl acrylate, and 9 parts of methacrylamide.
[0072] (2) Modified polytetrafluoroethylene (PTFE) water-based resin
[0073] Process: Add 30 parts of polytetrafluoroethylene (PTFE) water-based resin, start stirring, add the de...
Embodiment 2
[0077] (1) Synthetic acrylic water-based resin:
[0078] Process: Add butyl acetate solvent and 30 parts of mixed monomers, blow nitrogen gas → raise the temperature to 100°C → add various monomers and part of the initiator di-tert-amyl peroxide (DTAP) dropwise → keep warm for 1h → Add the remaining initiator dropwise → keep high temperature (130°C) for 3 hours → measure the conversion rate (96%) → desolventize → negative pressure desolventize → lower the temperature → add DP-518 dispersant surfactant → add deionized water → stir Disperse → control solid content → filter and pack for later use. The proportion of the main raw material mixed monomer: 40 parts of methyl methacrylate, 15 parts of methacrylic acid, 3 parts of acrylic acid, 12 parts of 2-ethylhexyl acrylate, and 5 parts of methacrylamide.
[0079] (2) Modified polytetrafluoroethylene (PTFE) water-based resin
[0080] Process: Add 60 parts of polytetrafluoroethylene (PTFE) water-based resin → start stirring, add th...
